I am stepping further into my Silverado SS
Current set up shorty headers into factory dual exhaust with muffler swapped to magnaflow.

Looking for gains on budget. OBX looks like the best bang for the buck but don't want plug wire hell.

Would pacesetters be worth the gains if I am going from a true dual to a y pipe set-up?? I don't have affordable quality muffler shop to connect pacesetters into my factory pipes.

 

I woulg go true duals. U can order the pipes to connect to ur headers. I was looking and found a couple places online. I ended up ordering 20ft of stainless 2.5 pipe and having my friend do the work at his exhaust shop. I couldnt be more happy. If u do cat delete ur gonna want a packed muffler like a magnaflow or corsa. Unless u just want it ungodly loud
